77968-43-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77968-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,6 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77968-43:
(7*7)+(6*7)+(5*9)+(4*6)+(3*8)+(2*4)+(1*3)=195
195 % 10 = 5
So 77968-43-5 is a valid CAS Registry Number.
